The Psychometric Properties of the Perth Emotion Regulation Competency Inventory (PERCI) in Sexual and Gender Minority Adults: Minority Stress and Resilience Correlates of Positive and Negative Emotion Regulation Difficulties

The Perth Emotion Regulation Competency Inventory (PERCI) is an emerging measure of positive and negative emotion regulation (ER) difficulties. We examined the factor structure and psychometric characteristics of the PERCI and its associations with psychopathology and minority stress in a sample of U.S. sexual and gender minority adults recruited through Prolific Academic ( N = 621). Confirmatory analyses indicate that the PERCI demonstrated good fit and invariance between sexual and gender minority participants and that the PERCI was reliable based on evaluations of internal consistency and test–retest reliability. Multilevel models suggest that positive and negative ER difficulties are relatively stable over a 3-month period and associated with proximal and distal minority stressors as well as resilience. Taken together, our findings indicate that the PERCI is a sound and useful tool to assess ER difficulties in clinical and research settings. Our findings also highlight the associations between minority stress and positive ER difficulties.
